12 - 14 June 2023

This week we are joined by Monique Rivera, assistant professor of entomology at Cornell AgriTech; Kerik Cox, associate professor of plant pathology; Līga Astra Kalniņa, Cox lab graduate student; and Anna Wallis, fruit IPM coordinator.

In this episode, Monique sits down with Kerik to talk about the big picture outlook on apple insects, and where things are headed for the future of pest management. Līga gives her latest apple disease forecast. Anna brings us her State of the State update on degree day accumulation and apple phenology. Recorded and released June 14, 2023.
